Alright a couple of things about our favorite blood doll...
When you fail to seduce, etc., you can immediately re-initiate conversation until you succeed.
When I succeeded, it gave me the "You roleplay the scared village girl and I'll rp the sexy vampire" in the blue persuasion dialogue font. I have a decent seduction stat (5) so I'm not sure if this is just in the wrong font or if it is actually using my persuasion (6). Either way, something is wrong.
I've haven't had the pink seduction text come up yet and I assume that her seduction levels are at the default levels (8+ish, iirc).
